The code prints an integral number like 4! But I'm actually a decimal number 4.4

I don't see why you need a left shift, the parseFloat function should do it.

JavaScript

total += parseFloat(arr[i]);// << 0;

Sample[^]

UPDATE: On the total, you might need to add logic to call toFixed method to control the decimal. I notice 4.4+4.4+4.4 = 13.200000000000001. With .ToFixed(2) the output will end up 13.20
